Vitamins for vision are necessary not only to improve the quality of vision, but also to prevent eye diseases. Medicines are selected based on the diagnosis, age and individual characteristics of the patient.
types of drugs
Vitamin complexes can be divided into 3 categories.
The first are preparations in which the main active ingredient is anthocyanin. This is a biologically active substance that has a pronounced antioxidant effect. Cranberry extract contains a large amount of anthocyanins.
The antioxidant acts as follows:
- protects tissues from free radicals;
- strengthens capillaries and vessel walls;
- prevents thrombosis;
- improves blood flow and metabolic processes;
- stimulates enzymatic activity.
The second group is made up of products that contain carotenoids, organic pigments that also participate in antioxidant protection. The most famous are beta-carotene, lutein and lycopene. They are able to slow down age-related degeneration of retinal tissue, reduce the risk of developing cataracts and have a preventive effect on other diseases.
The third group is complexes with microelements and minerals: zinc, selenium, calcium. Zinc is considered especially useful because it promotes the functioning of the optic nerves. Preparations with a high zinc content are used for glaucoma and other age-related pathologies.
Drops or capsules: which is more effective?
The form of the drug is chosen depending on the type of disease. In case of pathology of the cornea or lens, it is recommended to use drops that distribute quickly over the iris. For retinal diseases, take tablets or capsules. When they dissolve in the blood, they release active substances that reach the inner part of the eye (retina). With drops this effect is not possible.
Who needs eye vitamins?
It is recommended to take vitamins not only for serious pathologies or diseases. Dietary supplements are necessary for those who spend more than 5 hours a day in front of a computer screen, those who wear contact lenses and people over 40 years old, since during this period age-related changes associated with the deterioration of the quality of vision. period.
Mineral complexes are prescribed at the first signs of hyperopia or myopia, as well as symptoms of increased intraocular pressure.
Eye vitamins for hyperopia or myopia will not restore visual acuity, but will normalize metabolic processes.
What vitamins will benefit vision?
Even healthy people need bioactive substances. They protect the organs of vision from adverse external influences, nourish tissues and prevent the development of pathologies.
The main thing is to choose the right vitamins depending on your age and health.
Vitamin A
Retinol is responsible for visual acuity, color perception and regeneration. Strengthens the corneal tissue and normalizes the functioning of the visual organs. Retinol deficiency leads to the development of conjunctivitis and dry eye effect.
B Group
For the normal functioning of vision, 4 types of vitamins from this group are needed:
- thiamine (B1) stabilizes intraocular pressure, participates in the transmission of information to the brain and maintains visual acuity;
- riboflavin (B2) normalizes blood flow and metabolic processes, nourishes tissues, protects against the negative effects of ultraviolet radiation and is responsible for visual acuity during twilight;
- pyridoxine (B6) promotes the functioning of the optic nerve and participates in the transmission of impulses, reduces muscle tension and prevents nervous tics;
- Cobalamins (B12) stimulate blood circulation, protect the lens body from opacities and help the optic nerve function.
All vitamins in this group support the visual functions of the body.
Vitamin C
Ascorbic acid is a vision vitamin, necessary to strengthen blood vessels and reduce the risk of bleeding. Regular redness of the whites of the eyes indicates frequent damage to the capillaries and a deficiency of this bioactive element.
Vitamin C also stimulates collagen production and prevents the development of cataracts. It is necessary for protection against ultraviolet radiation and oxidation processes that occur in the human body.
Vitamin E
Tocopherol is responsible for antioxidant protection. It maintains the permeability of vascular tissues, thanks to which nutrients reach the cells more quickly. This element is present in most drugs that combat age-related changes.
Nuances of choice
When choosing eye vitamins to improve vision, you should pay attention to:
- composition (name and content of active substances);
- release form (drops or tablets);
- flavor (presence of flavoring and aromatic additives);
- contraindications and side effects;
- age;
- the presence of concomitant pathologies and diseases;
- Best before.
When acquiring vitamins to improve visual acuity and prevent eye diseases, you should not count on instant action. The effect occurs most often after completing 2-3 courses, the duration and frequency of which are determined by the doctor.
Natural sources of vitamins.
You can get vitamins not only from pharmaceuticals, but also naturally, from food.
Sources of retinol are blueberries, grapefruit, celery, green vegetables, apricots, and tomatoes. Thiamine can be found in legumes, bran bread, fish and shellfish. Riboflavin is found in green vegetables, salads, seeds and nuts.
Vitamin B6 can be found in liver and eggs, and B12 can be found in beef, milk, and dairy products. The source of ascorbic acid is citrus fruits. It is found even more in bell peppers, as well as in rose hips, black currants and raspberries.
Tocopherol deficiency can be leveled by introducing carrots, sea buckthorn, lettuce, greens, butter and eggs into the diet.
Conclusion
For the prevention or treatment of eye disorders, various vitamin complexes, drops and medications are prescribed. Remember that medications are prescribed individually, only by a doctor. If you choose them yourself, you risk making the problem worse.
Perhaps one of the most important and easiest ways to keep your eyes healthy is to have an annual eye exam with your eye doctor or ophthalmologist. At these visits, you can discuss your concerns and address your individual eye care needs.
